The Manchester derby was settled by a goal from local boy Marcus Rashford, but the ramifications could be felt far beyond Lancashire as Manchester City were left clinging onto their Champions League place with the title now an impossible dream.
Rashford has scored five goals in eight games since being brought into the United team and is flourishing in the limelight, says the Daily Mirror. "Nothing fazes him and City couldn't handle his pace and movement; he seemed to enjoy his battle with [Eliaquim] Mangala in particular."
The 18-year-old is now "central to Louis van Gaal's plans for the rest of the season", says the Manchester Evening News, which praises the player's "incredible" work rate.

"Pep Guardiola faces the possibility of managing Manchester City in the Europa League," warns The Times.
The good news for City is that the incoming boss has committed to taking over and cannot back out, says the Daily Mail. The Spaniard "had not banked on his new employers floundering so dramatically in the Premier League", but "does not have a clause in his contract wavering any deal should City not qualify for the Champions League".
